Abstract

The invention discloses a pulse supercharging exhaust pipe of an eight-cylinder diesel engine. The exhaust pipe comprises exhaust header pipes and exhaust branch pipes. The exhaust pipe is characterized in that: the exhaust header pipes and the exhaust branch pipes are co-wall pipes. The exhaust header pipes and the exhaust branch pipes are the co-wall pipes, and four exhaust header pipes are connected with a supercharger through a four-in-two pulse converter, so the exhaust pipe has simple and compact structure, reduces pipe fittings, reduces the cost, reduces the pressure loss of pipelines,and improve the work efficiency of the diesel engine.

Description

technical field [0001] The invention relates to an eight-cylinder diesel engine, in particular to an eight-cylinder diesel engine pulse supercharging exhaust pipe. Background technique [0002] Existing eight-cylinder diesel engine pulse supercharging exhaust pipe adopts in-line type, including an end-mounted exhaust gas turbo double-inlet supercharger, eight exhaust branch pipes, four exhaust main pipes and two two-in-one pulse converters, Metal bellows or metal gaskets are arranged at the junction of the exhaust main pipe or the exhaust branch pipe. The supercharged exhaust pipe not only has many pipe fittings and a complex structure, but also occupies a large area and has high cost. Contents of the invention [0003] The purpose of the present invention is to provide a simple and compact eight-cylinder diesel engine pulse supercharging exhaust pipe. [0004] The purpose of the present invention is achieved in this way, a pulse-charged exhaust pipe for an eight-cylinde...
